Specification of Letters Patent. i

Patented June 29, 1915.

Application filed September 3, 1913. Serial N o. 787,998.

To all whom t may concern:

Be it known that I, HERRIGK vAIKEN, a citizen of the Unitedl States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented a new and useful Lamp-Socket, of which the following is a specification.

This invention relates to a lamp support capable of general use, but particularly adapted for use on automobiles and the like. It is an improvement on an invention made by James C. Ramsey, J r., an application for patent on which was filed Oct. 31,I 1912, Serial No. 728,821. 1

The principal object of the, invention is to providel a simple and inexpensive construction for this purpose involving parts which can be separated readily when desired and including details of construction by which the lamp and the frame which carries it can be swung' through angles about different axes and by which they will remain in any position without the use of separate fastening devices. y

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which i Figure 1 is a side View of a portion of an automobile showing a preferred embodiment of this invention applied thereto; Fig. 2 is a sideview of the lamp and lits frame on enlarged scale showingl the'parts in central longitudinal section; and Fig. 3 is a sectional view on the' line 3 3 of Fig. 2.

The parts' are supported on a stand 10,

which has a verticalv part and-a cylindrical horizontal arm 11. This horizontal arm is .provided with a conical end 12 and with an integral collar 13 at the end of the cone.

The frame 15 for the lamp is provided with a hollow, externally screwthreaded projection 16 and with a. socket 17 fitting the end 12 and receiving it. At right angles thereto it is provided with another screwthreaded projection 18 having a cylindrical passage 19 therethrough. This frame also is provided with a vertical conical extension 20 at the top. This has a central passage 21 therethrough.

For the purpose of holding the frame 15 on the stand 10 a nut 23 is provided adapted to be screwed on the threaded end 16 and having an end vBange coming down beshaft 2G and fitting the passage frictionall)7 so that it will remain inlanyy position to which it is turned. It has a collar 27 thereon, and a nut 28 is provided for holding this in position in the frame. A hollow sheet metal rod 29 fits the projecting end of the shaft 2G and has a .loose lit in the end of the nut 28. This sheet metal rod is therefore 'capable of turning the shaft 26 when it itself is turned. On the end it is provided with a. handle 30 and with a pair of push buttons 31. s

On the inner end ofthe shaft l26 is splined a bevel gear 32. This meshes with a bevel gear 33 on lthe inner end of a hollow shaft 34 which extends through the passage 21. 0n the top of this shaft 34.- is screwed a hub 35 forming a part of the lamp body 3G. A nut 3 7 is shown for securing these-in position.

The wires for the lamp designated a and come up through the hollow stand 10 and one of them, as b, passes directly up through the hollow shaft 34 to the lamp c. The other one a passes in through the arm 11 along the interior of the hollow shaft 26 and rod 27 to the push buttons 31, then back again into theinterior of the frame 15 and up through the shaft 34 to thel other terminal ofthe lamp. The push buttons, by means well understood in the art, are designed to connect and disconnect the two-parts of the wire a so as to control the llightingof the lamp. In

this way it will be seen that the operator Although I have illustrated and described only a single embodiment of the invention I am aware of the fact that many modifications vcan be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, Ido not'wish to be limited in these'respects, but

What I do claim is 1. The combination with a stand having a *Iii at i

, provided With horizontal, cylindrical arm provided With a conical end, of a lamp supporting frame a socket fitting said conical end, and yielding means for forcing the frame along the conical end toward the cylindrical part.

2. The combination with a fixed support having a conical end and a stationary collar at the large end of the cone, of a frame having a socket for receiving said conical end, and a screw-thread on the exterior, a nut connected with said threads and extending beyond said collar, and a spring located between the collar and the end of the nut.

3. The combination Witha stand having a horizontal, cylindrical arm provided with a conical end, yof a lamp supporting frame provided with a socket fitting said conical end, and having a conical projection, and a lamp body provided with a conical socket for receivin -said rojection whereby the frame is he d frictionally on the support and the lam'p body is capable o1" being turned thereon on a different axis.

4. The combination with a support having a horizontal arm thereon, of a frame frictionally held on said arm and capable of turning about the axis of the arm, a lamp body connected with said frame and capable of turning on an axis at right angles to the first named axis, and means extending through said frame for turning the lampl body on its axis. y

5. The 'combination with a support having a horizontal arm thereon, of a frame frictionauy had turning about the axis of the arm, a lamp body connected with said frame and capable of turning on anaxis at right angles to the first named axis, and' means extending through said frame at right angles to both of said axes for turning the lamp body on its axis, and holding it rictionally in itsadjusted positions. g

In testimony lwhereof I have hereunto set my hand, in the presence of tvvo subscribing Witnesses.
